Dual Channel Central Office ADSL2+ Line
Driver
The EL1537 is a very low power dual channel differentiated
amplifier designed for central office line driving for DMT
ADSL solutions. This device features a high drive capability
of 400mA while consuming only 7.5mA of supply current per
amplifier from ±12V supplies. This driver achieves a typical
distortion of less than -75dBc, at 1MHz into a 50Ω load. The
EL1537 is available in the thermally-enhanced 28-pin
HTSSOP package. This device is specified for operation
over the full -40°C to +85°C temperature range.
The EL1537 has two control pins, C

disable modes. The EL1537 maintains excellent distortion
and load driving capabilities even in the lowest power
settings. The EL1537 has extended bandwidth and improved
THD and slew rate for ADSL2+ and VDSL applications.
